    摘要: A polishing apparatus has a turntable with an abrasive cloth mounted on an upper surface thereof and a top ring disposed above the turntable for supporting a workpiece to be polished against the abrasive cloth under predetermined pressure. The turntable is rotatable by a first motor through a timing pulley connected to the first motor, and the top ring is rotatable by a second motor through a timing pulley connected to the second motor. A torque detector incorporated in the timing pulley connected to at least one of the first motor and the second motor detects an output torque produced by the at least one of the first motor and the second motor.

    摘要: A polishing apparatus is used for polishing a workpiece such as a semiconductor wafer to a flat mirror finish. The polishing apparatus, includes a turntable having a polishing surface thereon, and a top ring for holding a workpiece to be polished and pressing the workpiece against the polishing surface on the turntable. A pusher is disposed in a position for transferring the workpiece to and from the top ring, and has a workpiece support which can be lifted to a position close to the top ring for transferring the workpiece to and from the top ring. When the workpiece support receives a polished workpiece and is lowered, a cleaning liquid is ejected substantially simultaneously from three cleaning nozzle units that are disposed in respective three positions to clean the upper and lower surfaces of the workpiece and the lower surface of the top ring.

    摘要: A polishing apparatus is used for polishing a workpiece such as a semiconductor wafer to a flat mirror finish. The polishing apparatus includes a polishing section for polishing a surface of a workpiece, a cleaning section for cleaning the workpiece which has been polished, a first liquid leakage sensor provided in the polishing section for detecting a liquid leakage which occurs in the polishing section, and a second liquid leakage sensor provided in the cleaning section for detecting a liquid leakage which occurs in the cleaning section. The polishing apparatus further includes a controlling device for stopping the supply of liquid to the polishing section or the cleaning section in which the liquid leakage occurs when either one of the first and second liquid leakage sensors detects the liquid leakage.
